Just as many ambient air issues with regard to the actual equipment operating environment are created by personnel and can be corrected by personnel, inlet air contamination is always created by humans and there is almost always a correction that will either eliminate the issue or mitigate the effect.
Analysis of the pressure data logging showed that, while the variable speed drive compressor maintained a constant discharge pressure near 120 psi, the pressure at various critical points fell to as low as 85 psi during peak production operations. General pressure in the plants, especially Plant 2, fluctuated between 102 and 112 psi, showing that the pressure/flow control valve was not regulating properly, and that Plant 2 lacked enough general storage volume to support transient flows.
The purpose of this article is to show there isn’t always a proportionally linear relationship between what happens with flow reductions on the demand side of a compressed air system - and what happens with the energy consumption in the air compressor room. Optimizing an entire compressed air system requires precise knowledge of the supply side, how compressed air is used in the process itself and how those two relate together.
Since completion of the system upgrade in the fall of 2020, PC Forge is on track to save an average of 1.9 million kWh and $266,000.00 per year in energy costs – and increase the production capability of its forging operation by 40%. The project also achieved a one-year payback with a \$245,000 incentive from Government of Ontario’s utility Independent Electricity System Operator (IESO).
The industrial internet of things (IIoT) and industry 4.0 have digitally transformed the way facilities operate, enabling processes that are smarter and more efficient than ever before. But digital transformation is still new to some and may seem abstract or ambiguous. In actuality, it’s quite the opposite.
This article discusses some experiences in using cellular connected data loggers to perform a compressed air assessment during a time when travel was restricted. While not ideal, this exercise identified huge savings for this customer.
Operating the vacuum system at higher levels (then necessary) affects the needed volumetric flow to compensate for leaks. This required compensation of volume (ACFM) must be added to the nominal production flow demand. The ambient air leak into the system will expand to the highest vacuum level, which is known as the “Expansion Ratio.”
What is vacuum as used in the manufacturing/industrial sector? The clearest answer is – a contained space with gaseous pressures much less than surrounding atmospheric pressure. Atmospheric pressure (ATM) is expressed in many units of measure. At room temperature a cubic foot of contained air at sea level – the random movement and molecular impact on the walls of the containment vessel equal a force of 14.7 psia for every square inch of the walls.
One of the best ways to reduce compressed air costs is to look for ways to reduce leakage flow, an unnecessary load that is a constant demand on the compressed air system. This flow is never-ending and occurs during production periods, and during quiet times at night or on weekends. Reducing the flow in a well-controlled compressed air system will result in the reduction of compressor energy consumption, usually by about \$1,750 per every 10 cfm, and often reduces pressure loss, allowing your machines to run better. This article discusses some recent experiences in using an acoustical imaging leak detector.
As part of its ongoing corporate initiative to find ways to reduce its energy bills, and the costly impact on the bottom line, a cleaning products plant, located southwest of Chicago, recently focused on improving their compressed air system operation. This company is a global leader in water, hygiene and infection prevention solutions and services. This article discussed their efforts to improve the operation of their compressed air system by implementing an innovative compressed air monitoring and control system.
Regular testing of pure gases helps to ensure the safety of consumers and of end products. Whether the pure gas is used directly for medical patients, or in the manufacturing of food, beverages, or pharmaceutical products, quality is of the highest importance. Inadequate levels of purity or unsafe contamination can be detrimental to the products or consumers.
